You don't know Jack may not have guns, exploding cars, or a cover system, but shit yeah I am more excited about this then any other announcement at E3. 
 
It's probably nostalgia but it's still true.

Very cool! It was fun to play and funny as hell back then, but it will be great as a party game on current consoles. Great news!

I can't wait for this, I put hours and hours playing the Originals and even the website game. This should be rad.

Sounds like fun!

Yes Cant Wait For This Game Thank GB Guys For Finally Getting Them To Make It

This could tie with the 3DS reveal for the best news to come out of E3 for me this year (if not surpass it, since I had no idea this was coming). I've been playing YDKJ for thirteen or fourteen years now, and can't wait for this to come out.

Epic news. I am IN when this comes out. Still own my YDKJ games...love 'em.
Remember playing Acrophobia online back in the day!

As a long-time YDNJ fan, I cannot...cannot...CANNOT wait for this game!

It will be a day long remembered.... the day when You Don't Know Jack returns to my life.

When I heard this news you would have no idea the amount of joy that filled my little heart. It's probably the best gaming news all this year. Anyway, day one purchase. No matter what.
